I have one rockford fosgate P2 12"---$50
and I have two Infinity Reference Series 12"s-- $200 obo, and i can throw in a dual 12" box for about 10 bucks

I bought the P2 about a year ago, I never used it, it is slightly used tho, and the Infinitys are about 2-3 months old, I really dont want to split them apart, but Im open to offers--No Lowballs-- I can also get a dual box for about $10, and can install them in the box before pick-up, just let me know if you are interested in the box...
